solve missing where cause error
I got this error : You are missing the WHERE cause.
But I have put HAVING into this syntax:
SELECT SUM(rating) AS starman_total_ratings FROM reviews GROUP BY movie_id HAVING movie_id = 6;
Challenge: We're in a movie database. There's a reviews table with the columns of id, movie_id, username, review and rating.
The movie "Starman" has the id of 6. Movie ids are found in the movie_id column in the reviews table. Write a query that totals up all ratings for the movie "Starman" in the reviews table. Alias it as starman_total_ratings.

While your solution would also produce the correct result, you don't need HAVING or GROUP BY for this challenge. You can replace them both with a WHERE clause, which is what the challenge is expecting to see.
